I had tried many applications for my few hundred mailboxes migration. But none of the application could be able to complete more than a couple of mailboxes migration. When I had contacted they started reporting that it is due to Office 365 throttling issue. Later out of curiosity I have tried EdbMails Office 365 migration with basic plan. EdbMails is the first application completed my 20 mailboxes migration successfully. Upgraded my migration plan and could be able to migrate all my Office 365 mailboxes without any issues. Last week did a re-migration and EdbMails is the only application does a perfect incremental migration without creating a single duplicate items on re-migration. Thanks to EdbMails, it is a hassle-free Office 365 migration software :)
